A method for producing an electrospun fibre, the method comprising: preparing a polymer matrix; adding a plurality of photoluminescent molecules to the poly- mer matrix to form a spinable solution, each photoluminescent molecule comprises a hydrophobic portion and a charged portion; and electrospinning the spinnable solution to produce the electrospun fibre. An example of the photoluminescent molecule is 1 -(1 -(8- pyridiniumoctyloxy)-2, 3,4,5- tetraphenylcyclopenta-2,4-dienyl)benzene chloride (structure shown below), a molecule having aggre- gation-induced emission (AIE) properties.
